DETAILED DESCRIPTION OF THE INVENTION

The inventors have found that reducers may be formulated from blends of VOC exempt solvents or low vapor pressure (LVP) solvents including a variety of compliant solvents to improve the thinning performance of the reducer with a number of different types of coating.

Embodiments of the present invention provide blends of LVP-VOC solvents having properties adequate to replace currently available solvents and solvent system used in the coatings industry. While blends of acetone and methyl acetate are well suited for thinning most oil based coatings, they typically are too fast drying for general use. Thus, embodiments of the present invention relate to blends of acetone and methyl acetate including one or a plurality of slower evaporating agents to improve overall performance of the reducers. In certain embodiments, the slower evaporating constituents include parachlorobenzotrifluoride (PCBTF), hydrocarbon LVPs, propylene carbonate, glycol ethers, diols, glycols, acetates, polyols, amines, amides, siloxanes, alkyl methyl esters, similar slower evaporating constituents, and mixtures or combinations thereof.

The exact choice of LVP solvent will depend on the solvency requirements for the particular coating in question. Hydrocarbon LVPs typically blend well with oil based coatings, but suffer from low solvency when used alone and have extremely low evaporation rate. Acetone alone has good solvency, but evaporates very quickly and is too polar to be compatible with many oil based coatings. A blend of acetone with an LVP hydrocarbon provides higher solvency early in evaporation of the solvent from the coating, while the LVP hydrocarbon slows a rate of solvent evaporation later in evaporation of the solvent system from the coating. One potential problem with this simple blend is that hydrocarbon solvents generally have low solvency that may lead to issues after all of the high solvency acetone has evaporated. A possible solution to this problem is through the incorporation of a slower evaporating solvent or a mixture of slower evaporating solvents, which act to increase the solvency of the blend as the acetone evaporates. Such slower evaporating solvents include PCBTF, Soy methyl esters, surfactants, heavy aromatics, glycols, other suitable LVPs and/or exempt VOCs, and mixtures or combinations thereof. Small amounts of surfactants, non exempt solvents, fragrances, hydrocarbons, etc. may also be added to improve capability of the mixture with the coating composition. For example, a blend having a high percentage of acetone and smaller percentages of methyl acetate, PCBTF, Soy methyl esters, dibasic esters, surfactants, hydrocarbon LVPs, hydrocarbons, glycol ethers, polyols, ethyl lactate, d-limonene, triethanolamine, propylene carbonate and other ingredients have been shown to be advantageous in reducing typical coating compositions.

Embodiments of the reducer compositions of this invention relate to acetone based, acetone and methyl acetate based or methyl acetate based composition including one compound or a plurality of compounds selected from the group consisting of VOC exempt compounds, LVPs and small amounts of nonexempt VOCs as needed. The goal is to produce a reducer that can replace traditional solvents and solvent systems for use with oil based coatings with very low levels of nonexempt VOCs to meet regulations such as those outlined by South Coast Air Quality District (SCAQD), California Air Regulatory Board (CARB), Ozone Transportation Commission (OTC), and the Environmental Regulatory Agency (EPA).

Certain embodiments of this present invention include a water based reducer including blends of exempt VOCs, exempt VOC and LVPs, combinations of LVPs or combination thereof and a small amount of nonexempt VOCs as needed. The compounds listed herein comprise members of these classes of exempt VOCs, exempt VOC and LVPs and other exempt compounds. A typical example includes a water base including smaller percentages of PCBTF, dibasic ester, methyl esters, hydrocarbon LVPs, surfactants, emulsifying agents, methyl cellulose, ethyl lactate, d-limonene, tall oil fatty acids (or their salts), linseed oil, propylene carbonate, fragrances, triethanol amine, etc.

Such mixtures may easily be blended to form emulsions by those skilled in the art. Emulsions as well as micro-emulsions of these blends are included in this technology. An emulsified blend of these constituents has the advantages of reducing odors associated with some of the constituents, such as PCBTF. In addition, the emulsions have the advantage of reducing cost and total VOC content due to the water. The use and development of emulsions is well described in many publications; however, the use of blends of VOC exempt solvents, combinations of VOC exempt solvents and LVP and combinations of LVPs in such applications has not been widely addressed in the prior art. Rauls et al in U.S. Pat. No. 6,156,833 describe water based blends of water from 68-92% with methyl soy esters from 15-20%, along with small amounts of other additive (surfactants, emulsifying agents, 2-amino-2 methyl-1 propanol, acrylic acid thickeners, fluorosurfactant, polystyrene blended with soy methyl esters, drying agents, anti-skin agents, a blend of polyethylene and paraffin wax, dimethyl polysiloxane, tall oil fatty acids, acrylic emulsion, waterbased Raw Umber dispersion and tinting agents. Bortz et al in U.S. Pat. No. 7,785,413 disclose water based emulsions based mainly on Soy methyl esters and dibasic esters along with exempt VOC solvents. However, neither patent exploits the use of LVP solvents and mixtures thereof as set forth herein. In fact, most of the solvent systems are currently too expensive to be practical as a major components of the reducer composition, such as purified soy methyl ester based solvent systems. Moreover, solvent system having high levels of Soy methyl esters will also certainly increase the curing time of most coatings if used to exclusively reduce the coating. The Soy methyl esters also degrade over time, if not preserved properly. The present inventions allows for formulations of relatively inexpensive, effective reducer composition that have only low levels of nonexempt VOCs, where reducer compositions include a variety of VOC exempt solvents, combinations of VOC exempt solvents and LVPs and blends of LVP solvents.

Embodiments of the reducer composition of the present invention provide a means to thin either oil based or water based coatings as well as potentially improving the overall qualities of coating compositions to better suit that of the user. Most of water based reducers of this invention are designed to decrease the viscosity of the coating, adjust drying times, improve wet edge, increase brush stroke, improve coverage, improve the resistance to dirt, reduce the growth of mold, increase leveling, decrease hazing, decrease orange peel, etc. Typical additives used in such water based reducers include, without limitation, fluoropolymers, silver complexes, rheology control agents, stand oil, linseed oil, alkyds, guar gum, Arabic gum, fatty acids, salts of fatty acids, paraffin waxes, polyolefin waxes, halogenated paraffin waxes, polystyrene, polyacrylic acids and copolymers, polyacrylates, polyacrylic esters, polyesters, glycols, silicones, polyglutamic acid, sodium methyl allyl sulfonate, erucic acid amide, capsaicin, ammonium bromide, polymeric amino phosphate(flame retardants), Oxylink™ (a trade name of Buhler, Inc), silanes, silicones, organic metal agents for crosslinking, corrosion inhibitors (for example, sol-gels), polymeric spherical particles (oxidized, EverGlide UV 691 from and a trade name of Shamrock Technologies), polyethylene/silica dispersion (Ultramatte UV 50-GDA, from and a trade name of Shamrock Technologies) and polyglycols.

These compositions are effective in reducers for oil and water based paints. They are particularly effective at reducing or diluting water based paints. In some cases, they can improve properties of the paint, such as wet edge, dry time, brush stroke length, stain resistance, mildew resistance, coating hardness, coating adhesion and more. These blends can also be easily adjusted by someone skilled in the art to meet the new VOC limits imposed by many government agencies. The renewable content could also be increased, if necessary.

Suitable Reagents for Use in the Invention

Suitable LVP-VOC solvents useful in the compositions of this invention include, without limitation, acetone, methyl acetate, parachlorobenzotrifluoride (PCBTF), benzotrifluoride (BTF), perchloroethylene (PERC), cyclic, branched, or linear completely methylated siloxanes, propylene carbonate, dimethyl carbonate, tertiary butyl acetate (TBAc), halogenated compounds, other solvents outlined in the List of Exempt Compounds in 40CFR 51.100 (s), and mixtures or combinations thereof. In addition, a number of LVP products are exempted by a number of requirements outlined in CARB (California Air Regulatory Board, Regulations for Reducing Emissions of Consumer Products 94508 (a) (94) generically by several definitions). Such solvents or compounds include solvents or compounds having vapor pressures less than 0.10 mm Hg. Generally, these compounds evaporate very slowly and have very low rates of evaporation. Manufacturers have been qualifying a number of solvents or compounds as LVP certified, based on CARB requirements.

Typical examples of VOC exempt solvents and LVP solvents each have limitations alone. Therefore, we have undertaken to develop advantageous blends of VOC exempt solvents, combination of VOC exempt solvents and LVPs and blends of LVPs. CARB has issued a list of accepted LVP solvents in 2003 (attachment E, CARB LVP-VOCs to be Individually Reported from their 2003 Consumer & Commercial Products Survey . . . ), which is incorporated by reference. A number of these compounds have specific advantages to those skilled in the art of reducing coatings. Some examples, include, diols, esters, glycol ethers, glycols, amines, hydrocarbons, amines, phthalates, etc. Some of the most advantageous blends are those of VOC exempt solvents and LVPs together. Acetone is one of the least expensive exempt VOC solvents, with high solvent strength. However, acetone alone is too fast for most reducing applications due to its high rate of evaporation. A combination of Acetone and Soy Methyl Esters has been shown to be advantageous for thinning Lacquers (Bortz U.S. Pat. No. 7,785,413). The Soy Methyl Esters have been listed as an LVP solvent, but they are expensive and are prone to degrade over time if not preserved properly. In addition, we have found that this blend is not as advantageous for reducing other coatings, such as paints, varnishes, epoxies, etc. Most standard paint thinners, varnish thinners, epoxy thinners and even lacquer thinners are complex blends of solvents. Some of the solvents are used to increase solvent strength (measured in some cases by Kb value or estimates thereof) and other solvents are included in blends to mitigate the rate of evaporation of the mixture. Standard paint thinner is typically a complex blend of various aliphatic and aromatic hydrocarbons. Duplicating the performance of such a complex blend can be challenging. We have discovered that that it can be advantageous to employ a number of Low VOC solvents or blends of LVP solvent, VOC solvents blends and mixtures thereof to achieve similar performance to the standard reducing agents currently on the market.

Acetone and water are the obvious, low cost options for reducing blends. However, both water and acetone tend to evaporate too quickly alone. Worse, they are both poor solvents for many oil based coatings. Even water based coatings suffer some loss in performance, when diluted or reduced solely with water. On the other hand, US Patent Application 2007/0101902 A1 teaches that a blend of only methyl soy esters and dibasic esters may be suitable for this application. These blends do have low odor and have high renewable content, but evaporate so slowly that they can significantly increase the drying time of a coating as well as being expensive. Less expensive hydrocarbon LVP products obtained from nonrenewable sources also extend the drying times of paints and lack the solvency to effectively reduce or dilute many coatings. Simply put, there is a need to develop new blends that mimic the properties of standard solvents, such as methylethylketone (MEK), xylenes, mineral spirits, turpentine, toluene, glycol ethers, alcohols, etc. and mixtures of such solvents.
